Wasserbeschaffenheit - Bestimmung von gelöstem Bromat - Verfahren mittels Ionenchromatographie (ISO 15061:2001)
Diese Internationale Norm legt ein Verfahren zur Bestimmung von gelöstem Bromat in Wasser (z.B. Trinkwasser, Rohwasser, Oberflächenwasser, teilweise behandeltes Wasser, Badewasser) fest. Durch eine geeignete Probenvorbehandlung (z.B. Entfernung von Chlorid, Sulfat, Metallen, Vor-Anreicherung oder Verdünnung) ist ein Anwendungsbereich von 0,5 µg/l bis 1000 µg/l zu erreichen. Der Arbeitsbereich ist durch die Kapazität der gegebenenfalls eingesetzten Vor-Anreicherungssäulen und durch die der Trennsäule begrenzt. Eine Probenverdünnung in den Arbeitsbereich kann erforderlich sein.
Qualité de l'eau - Dosage du bromate dissous - Méthode par chromatographie des ions en phase liquide (ISO 15061:2001)
La présente Norme internationale spécifie une méthode de dosage du bromate dissous dans l'eau (par exemple, eau potable, eau brute, eau de surface, eau partiellement traitée ou eau de piscine). Un prétraitement approprié de l'échantillon, par exemple par élimination du chlorure, du sulfate, des métaux, préconcentration ou dilution, donne une gamme d'applicabilité de 0,5 gg/l à 1000 gg/l de bromate dissous. Le domaine de travail est limité par la capacité d'échange ionique de toute colonne de préconcentration utilisée ainsi que par celle de la colonne de séparation. Une dilution de l'échantillon dans la gamme de travail peut être nécessaire.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 15061 was prepared by Technical Committee ISO/TC 147, Water quality,
Subcommittee SC 2, Physical, chemical and biochemical methods.

Introduction
The essential minimum requirements of an ion chromatographic system applied within the scope of this
International Standard for the determination of dissolved bromate are given in clause 5.
The diversity of the appropriate and suitable assemblies, and the procedural steps depending on them, permit a
general description only.
Further information on the analytical technique can be found in the normative references (clause 2) and the
bibliography.
INTERNATIONAL STANDARD ISO 15061:2001(E)
Water quality — Determination of dissolved bromate — Method by
liquid chromatography of ions
1 Scope
This International Standard specifies a method for the determination of dissolved bromate in water (e.g. drinking
water, raw water, surface water, partially treated water or swimming pool water).
Appropriate pretreatment of the sample, for example by elimination of chloride, sulfate, metals, preconcentration or
dilution, gives a range of applicability of 0,5µg/l to 1 000µg/l dissolved bromate.
The working range is restricted by the ion-exchange capacity of any preconcentration columns used and that of the
separator column. Dilution of the sample to the working range may be necessary.

3 Interferences
3.1 The presence of nitrate, chloride, carbonate and sulfate may affect the capacity of the concentrator column
and lead to poor recovery of bromate (9.2.1).
3.2 The presence of chloride, sulfate, carbonate and hydrogen carbonate can cause interference with the
determination of bromate (9.2.1). Depending on the column utilized, other ions may interfere; this should be
checked.
3.3 Metals present (e.g. barium and silver ions released from sample pretreatment steps) will bind to the resin
material of concentrator and separator columns, resulting in a loss of performance. Metal ions may be eliminated
with the aid of a metal clean-up column or special exchangers (see Figure 1 and clause 9).
ISO 15061:2001(E)
3.4 The interference of some organic acids with the determination of bromate was checked and found not to be
significant to the concentrations tested (annex E).
